TO ALL WHOM IT MY CONGERN: p

Be it known that I, GILBRT LEVETTE, ofV the-eity of Indianapolis, countyot' Marion, und State of Indiana, have invented a. new and useful Device for Displaying Advertisingards Automatically by `Means of the Time-Keeping Mechanism of Clocks; and I dorhereby declare `that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, making' part ofthe specitication.

My invention relates to the display of adrertisingcards in hotels, depots, and other public places, in a.

manner that combines attractiveness and'prominence with compactness and neatness, and lconsists in connecting Vthe cards together -on an endless band-or apron, arranged within the clock-case, and exposing them to view, one

or more at a time in intermittent succession, automatically, by means of suitable mechanism, that is connectedV with and controlled by'the timekeeping movement of the clock.

Figure 1 is a front view of a clock havingr my advertising-device attached, the door and dial-plate being left oiffto sliow the works. Y

' Figure'2 isasi'de view, showing the works in elevation, and the case and advertising-device in section.

Figure 3 isa. detached view of the device for controlling the action of the advertising-mechanism.

Figur-e4 is a perspective'view of the catch-K enlarged.V

Similar letters of reference indicate corresponding parts in the several gures.

The following description will enableskilled artisans to make and u se my'invention.

A is the clock-ease, which may be of any style or finish applicable to this purpose. My advertising-device may be attached' to almost any style ot' clock, with -or without strikingr-mechanism,` or whether operated by weights or springs; but I prefer having the time-keeping movement and case, aswell as the advertisingmechanism, made for the purpose, as being cheaper'andneater. I

The advertising-'device consists'of an endless band, B, hung over a rollerC, that revolves freely on pinions, having their bearings in the uprights D. The band B may be ot any length. or width desiredto hold any size or number of cards,having reference, ofcourse, to the dimensions of the clock-case, and the capacity of' the actuatingmechanism. i Y Y The cards are printed on', or in any suitable. manner aixed to, the band B, which is hung over the roller C, so that the cards may be'drawn up opposite a glazed opening in the door` of the clock-case, through'whioh they are exposed to view. The position o t' the opening, which is opposite the top'card, is indicated by the'red dotted lines X Y in tig.' 2'. l l

The cards are exposed to view in intermittent succession, automatically, by means of /the' train of wheels 1 2 3 4 5, actuated by afcoiled spring, applied to wheel l in the same mannerras applied to the timekeeping and striking-movements of clocks. i Y

Tothe end of the shaft of wheel 5, and front `of .the plate .which secures the movement, a crank, G, is y xed. This crank is connected, by a rod, E, to a vertical sliding rod', F, to the lower end of whichis attached a exible arm, I, terminating in a. forked catch, K, 4in the position shown in tig. 1, so that the catch will stand about the middle of the belt B.

The catch K, which is more clearly shown in g. 4, is arranged at the rear ofthe band B, and is held close to it by the exible arm I, so that the lower ends of the little triangular pieces at .each side will catch upon. the

horizontal rods L, attached to the band B, between the cards, for this purpose, as the rod F descends', as hapel after described. 1

Theinclined edgesoi' the triangular pieces press the catch K back as it passes the rod Lin ascending, so l,

as to prevent it catching against them. I

E E are guides for theends of the rods L, and, with the uprights D D, kecp'tlie/band B'inplace.

P is a springcatch`, attached by its upperend to the upright, D, and having its lower end bent to rest on the rods L, to keep the weight of the band on the front from drawing it back. The spring'catch P allows the rods L to pass freely asthe bandis pushed down by the arm I, but preventsthem from moving in the-opposite direction. l i A l The position of rod F, arm I, and catch K, as represented in iigs. 1 and 2, is about midway of its upward movement, preparatory to catching upon the next horizontal rod L on the band to push' it down.

'The weight of the catch K, arm rod F, andy connecting-rod H, is vbalanced by the enlarged, elongated portion of the crank G1, opposite the wrist to which rod H is attached, in order to` make the motion' of the rod F morefsteady. I

` Without control, the action of the springattached to wheel 1, upon the'tr'ain of wheels 1 2 S 4 5, and crank G, would be t'o cause a continuous rotary motion, that would give the rod F,`arm-I, and catch K, a rapid recip rocating motion, and actuate the card-band B, and shift the cards with corresponding rapidity'. This action isvz controlled by means of-a disk, M, which I place on the shaft ofthe escapement-wheel of the clock.

The disk M is furnished with pins, N, set in 'its face near the periphery, that engage withv an arm or pawhg' o n the same shaft with wheel 5 and crank G.

l The'escapement-wheel and disk M revolve in the 'direction indicated by the arrow on the' disk, and the pawl O rests aga-inst one'of the pins N, preventing'any action .ofthe advertisingmechanism until lthe disk M is revolved to carry the pin beyond the end of the paivhwhich, being then released, allows the advertisingmechanism to revolve the crank Gr, and'actuate the vertical reciprocat'ing'rod F, arm I, and catch K, which, on descending with a quick, strong movement, catches upon one of the horizontal rods L on the card-belt, pushes it down from the r'earlthe width-of a card, and raises another card'up onl the front, opposite theglaz'edfopenng in the door. v

The number of pins N setv in the disk M is determinedl with reference to the time it is desired to expose. each card; and the diameter of disk. M and the pins N is arranged with reference to-the length of pawlO, So'

that, when 'the card has been shifted, as just described, the vfurther revolution of the crank G will be'arr'ested by the pawl O engaging with the next-pin N in succession; and thus the operation of releasing and engaging of the time-keeping movement.

the pawl O by the pins Nin disk M goes' on\ ai1tomatically controlled and regulated by the escapernent-Wheel In the modelrepresented by theaccompanying drawing, the escapement-wheel, on the'shaft of which disk M is fixed, revolves about three times `per rninute;fand, therebei'ng five pins on the disk,'th'e exposure of the cards'will be about-four seconds each, or fteen cards per minute.

In order that the time-keeping movement Ashallnot be affected by the action of the advertisingmcchanism,

- the pawl O is so arranged that, when it is arrested' by the pin N, as described, it will strike the pin directly in `a line drawn through thecentre of the shaft of the escapement-wheel and the pin, so that Vthe blow from the pawl will neither accelerate nor retard the movement ofthe escapementlwheel, as would be the caseif the pawl were arrested by the pin'when in'- any other position. This particular vfeature of my device is of vital importanceto the practical combination of the advertising with the timekeeping mechanism, in order-that the aceu.

racy of the latter shall not b e affected thereby.

- .The position ofthe pin'N, when'it stops the pawl O, is clearly shown in fig. 3,'beingin the angle of a right angle, formed by thea-ed dottedlines, drawn along the edge of the pawl, and through the centre of the pia N and shaft of the eseapement-wheel.

` The rods L, attached to the belt B across its face, are placed equidistant from eachother, for the-catch K to take-'hold of' to' shift the cards', ais-before described. The rods may be of ornamental moulding, to mark the -divisons between the cards. The ends of the rods project beyond the` edges'ofthebelt into the guides E, that keep them in place. v

The-guides E are curved at the bottom,`to collect the rods together, t'the band arranging itself in folds, as

represented' by thercd lines B B, in fig, 2, thus admitting the use ofa longer belt, and, consequently, greater pins N, as and for the purpose set-forth.

number of cards within a given space.

I do no t confine myself to any particular number or arrangement of wheels` employed in the advertisingmechanism, as these may'be-vared at convenience, to sut vaiious constructions of clocks.

Having thus fully` described my invention, what 1 claim as new, and desire to secureby Letters Patent,`s-

The disk M and` pins N, ontheshaft of the escapement-wheel ofV the timekeeping movement, for con- I trollingiand regulating the action of the advertising-mechanism, substantially as' and for the purpose set forth. v 2.

The rods L, or their equivalents, attached to the advertising-band B, as and for the purpose s'et forth. 4.
